Introduction to genetics

As human become smarter and are able to do things they only imagined, ethical questions pops up. I am talking about genetic engineering. Genetic engineering is when we mess with the gene structure of a living thing. We have used it on corn so it can grow bigger. We have also added a gene to a fish to make it glow in the dark. But when you really think about this is it ethical to do all this? Is it ethical to mess with the genetics of a plant so we can use it to our advantage? Are we trying to playing God's role by doing this? Who should decide if this is ethical or not? Who has the power to stop this or keep it going? This are questions I plan to answer in my research. As a student that is interested in science, this topic is based on science. I hope one day I can become a scientist and put in my own information for this topic.
